European shares end week on a high after US jobs report

European stocks closed in positive territory on Friday, ending the week on a high amid increasing hopes of a European Central Bank (ECB) bond-buying program, and after U.S jobs figures came in marginally weaker than expected.

The U.S. Labor Department report showed 192,000 new jobs were created last month, slightly less than the 200,000 forecast. The unemployment rate remained unchanged at 6.7 percent.

"I think this is enough of a goldilocks number for the market – it doesn't change Fed tapering, but still signals the economy is expanding gradually," Anthony Valeri, an investment strategist for LPL Financial, told CNBC.

In Europe on Thursday, the European Central Bank (ECB) opted to keep monetary policy unchanged, despite some calls to act to quell disinflation, which could damage the region's economy.

ECB President Mario Draghi, however, stressed that the central bank remained committed to the use of unconventional policy measures if required - a sentiment reiterated by the ECB's vice president to CNBC on Friday.

Speaking at the Ambrosetti Forum in Italy, Vitor Constancio said an ECB bond-buying, or quantitative-easing (QE), program had been discussed at the monetary policy meeting, although not in detail.

"We did not discuss details (of QE) because that was not the environment to do it," he told CNBC. "We have had some discussions (in the past) and we will have more, about the details... of course, the details are important."

Draghi has repeatedly said there are other policy tools the ECB could use -- and some of the more unconventional measures have recently garnered attention.

Ahead of April's monetary policy decision, Germany's Bundesbank President Jens Weidmann stoked speculation by saying QE had not been ruled out. Unlike central banks in the U.K., U.S. and elsewhere, the ECB has not launched a bond-buying program, and speculation that one might be in the works has given stocks a boost.
